    knotty: Fix output buffering issues
    
    We need to flush the footer removal, else it may not be outputted until
    the buffer is flushed as part of StreamHandler and this would lead to
    it removing the ERROR output just printed which is extremely confusing.
    
    Also ensure the footer is cleared before printing a summary as in
    some cases it wasn't being removed, also leading to user confusion.
